ABSTRACT
Wood is an organic material formed by the growth of cells in living trees. The trees produce this organic matter by the conversion of sap to carbohydrates . This process is aided by photosynthesis . Foodstuffs are consumed in the cambium to form living cells containing protoplasm . These cells subsequently modify and lignify to form the different classes of wood cells. Wood cells are composed mainly of cellulose and the cementing agent lignin . Most woods are slightly acidic.
